Application filed June 27. 1901. Serial No. 66,803- No model.)

To all whom it may concern;

Be it known that I, SOLOMON R. WAGG, a

citizen of the United States, residing at Ap useful improvements in refining-engines, and

has for its general object to provide an improved construct-ion of blade and an improved arrangement of the blades about the core or cylinder and shell of the engine.

Other objects of the invention relate to details of construction and to combinations and operations of parts.

My invention has special reference to improvements in refining-engines of the Jordan type and will be so described; but it will be understood by those skilled in the art that said invention and improvements may be applied tootherforms of refining-engines.

I have illustrated the invention in the accompanying drawings, in which Figure 1 is a section through a refining-engine, the blades being shown arranged on the roll in groups of two each. Fig. 2 is a section through a spacing-block. Fig. 3 is a section through a blade. Fig. i is a section through a filling-strip. Fig. 5 is a broken sectional view of a portion of a roll, the blades being shown arranged on the roll in groups of three each. Fig. 6 is a similar view showing the blades grouped in series on the shell.

Referring now to the drawings, 1 indicates the shell of anordinary Jordan engine, and 2 the cast-iron conical core or roll rotatably mounted therein in the usual manner. At

intervals about the surface of the roll 2 are opposite sides with a longitudinal groove 6, I

the purpose of which will be presently explained. Each of the blades 5 comprises a bar of metal provided on one side with alonwith a corresponding tongue 8.

In order to the full understanding of my invention and of the advantages thereof, it is necessary first to state that inthe ordinary Jordan engine each blade is set in its own groove on the roll, and arelatively wide space is provided between adjacent blades for the passage of the stock from the inlet to the outletend of the engine. As commonly constructed a Jordan roll is four feet long, two feet in diameter at the large end, and one foot in diameter at the small end and is provided with thirty six full-length and gitudinal groove 7 and on the opposite side thirty-six half-length bars, presenting two hundred and sixteen linear feet of working surface.

According to my invention instead of equally spacing the bars apart I group a number of blades to form a composite bar, only separating the blades of each group or series by a narrow filling-strip, and between adjacent groups of blades I provide a space for the passage of the stock. The blades may be arranged in groups of two, three, four, or more; but four blades will generally constitute the maxim umnumber. By grouping the blades in the manner set forth herein I can greatly add to the linear working surface of the cone and at the same time preserve sufficient space for the passage of the stock. In actual practice by using four -bladed and three-bladed bars the working surface of a roll has been increased from about two hundred and seventy linear feet to nearly seven hundred linear feet.

I will now describe in detail the manner of mounting the blades on the roll. In case it is desired to group the bladosin series of two each a blade 5 is placed adjacent to a rib 3, with its tongue 8 inserted in the groove 6 of said rib. A filling-strip 9 is next placed adjacent to the blades. This filling-strip may be of wood, lead, or steel, is of .less width than the blade, and is provided with a corresponding tongue 10 and groove 11. When'placed adjacent to the blade, the tongue 10 of the filling-strip 9 will fit into the groove 7 of the blade. A second blade 5 is now placed adjacent to the filling-strip 9, its tongue 8 fitting into the groove 11 of said filling-strip.

On the opposite side of the space 4 two blades 5, with an interposed filling-strip 9, are similarly arranged, and then a spacing-block 12, having on opposite sides tongues 13, is driven in between the two sets of blades, the tongues 13 fitting into the grooves 7 of the two innermost blades. In like manner the other spaces 4 around the roll are provided with blades. By forming the blades 5, the filling-strips 9, the spacing-blocks 12, and the ribs 3 with the various corresponding tongues and grooves described it will be seen that said blades, filling-strips, and spacing-blocks will be securely locked together and to the ribs 3 and cannot be thrown out by centrifugal force when the roll is revolved. The spaces 14 between adjacent pairs of blades formed by the ribs 3 and the similar spaces 15 formed by the spacing-blocks 12 are for the passage through the engine of the paper-stock. As shown in Fig. 5, the blades may be grouped in series of three each, in which case the spacing-blocks 12 are made proportionately narrower.

By enlarging the space between the ribs 3 it will be evident that the blades may be arranged in groups of four, five, or more and a spacing-block 12 of the same width shown in.

Fig. 1 be employed, thus preserving the enlarged space 15 between the groups of blades. In like manner and as shown in Fig. 7 the shell 1 may have its blades 16 arranged in groups; but it is not ordinarily desirable to materially increase the working surface of the shell.

It will of course be understood that instead of the special construction of roll and blade shown I may employ the ordinary fiat blade in general use and any preferred construction of roll that will admit of the blades being arranged as shown and described herein, the blades being also secured to the roll in any preferred manner, the broad principle of the invention, so far as the arrangement of the blades is concerned, consisting in grouping the blades in series of two or more to form a composite bar.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a refining-engine, a roll having thereon longitudinal ribs ali'ording between them spaces, a number of blades located in each of said spaces, and a spacing-block inserted between the adjacent blades in each space for locking the blades in place and separating them into groups or series containing two or more blades, the blades in each of said groups or series being separated from each other by means of filling-strips of less width than said spacing-blocks.

2. In a refining-engine, a roll having thereon longitudinal ribs grooved longitudinally on each side and afiording between them spaces, a number of blades located in each of said spaces,each of said blades having atongueand a groove, and spacing members inserted between adjacent blades and havingcorresponding tongues and grooves, whereby, when in position on the roll, the outermost blades of each series will interlock with the adjacent rib, and the spacing members will interlock with said blades.

3. In a refining-engine, a roll having longitudinal ribs thereon affording between them spaces, a series of blades located in each of said spaces, the outermost blades of each series having a tongue-and-groove connection with the adjacent ribs, and a spacing member inserted between adjacent blades and having a tongue-and-groove connection therewith.

4. A blade for refining-engines having on one side a longitudinal groove extending throughout its length and on its opposite side a corresponding tongue.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

SOLOMON R. WAGG.
